I'm running a IDE and SATA drive on my computer and they run well, though the IDE is a little slower but not much, both are 5400rpm drives. Both are formatted as NTFS drives. I would suggest you run the same brand as you have currently equipped on your computer to avoid compatibility problems. This is especially trouble if your doing a master/slave configuration. By the way, almost all drives are IDEs; mostly they've just changed the name and the wire they use.
Okay I got my comp a coupla years ago and I am really needing a new hard drive.I've been thinking about getting a Maxtor Basic 300 gb Internal drive but Im not sure if its compatible because it says its for ATA.My question is do I have a ATA or IEDE connection?
